A device for sensing a concentration of a combustible specie of interest (10, 20, 30, 50, 60) and a process analytic system (300) employing such sensors (10, 20, 30, 50, 60) are provided. The sensors (10, 20, 30, 50, 60) generally include a treatment or material that is adapted to increase the resistance of certain portions of the sensors (10, 20, 30, 50, 60) to exposure to sulfur. In one aspect, an improved sulfur-resistant process analytic system (300) includes a probe (302) with one or more sulfur-resistant sensors (10, 20, 30, 50, 60) therein coupled to a controller (308), a thermal control module (304), and a source of blowback gas (306).
